Frequently Asked Questions

How do you install a Ballistic Engineering drop-in trigger?

Begin by placing the trigger unit into the AR-15 lower receiver housing, aligning it with the pin holes. Install the trigger pins, then use a small hex wrench to tighten the internal set screws for proper tensioning against the receiver floor. Finally, perform dry-fire pulls to confirm reset.

What tools are needed to install an AR-15 drop-in trigger?

Essential tools include the drop-in trigger itself, an AR-15 lower receiver, a vise (like the Real Avid Smart-Vise), a bench block, and a small hex wrench for adjusting the trigger's internal set screws.

What is the benefit of a drop-in trigger for an AR-15?

Drop-in triggers, such as the Ballistic Engineering model, significantly enhance the shooting experience by offering a crisper break and a shorter reset compared to standard mil-spec triggers, leading to improved accuracy and control.

How do you adjust the tension on a Ballistic Engineering drop-in trigger?

Tension is adjusted using internal set screws located on the trigger unit. A small hex wrench is used to tighten these screws, ensuring the trigger is securely tensioned against the receiver floor for optimal function and reliability.
